   In a tower defense game, a tower that should target the enemy with the highest HP sometimes targets the enemy with the lowest HP. The targeting code sorts enemies by HP. What type of defect is this?

   • AA design flaw in the targeting system, where the intended target is actually the lowest HP.
   • BA boundary issue in the enemy list, where the first enemy is always selected.
   • CA logic error in the sorting algorithm, where the sort order is reversed.
   • DAn unintended interaction with the tower's range, causing it to target a different enemy.

   During playtesting of a racing game, players report that cars sometimes flip over when hitting a specific curb at low speed, but not at high speed. What should you investigate first?

   • AThe collision detection code for that curb, looking for a boundary issue in the physics response.
   • BThe car's suspension settings, which may be incorrectly tuned for low-speed impacts.
   • CThe player's input, because they may be pressing the brake or steering at the wrong time.
   • DThe track design, because the curb may be placed at an angle that causes flips.

   In a puzzle game, a block that should slide only when pushed from the left also slides when pushed from the right. The tester reports this as a 'block slides from wrong direction.' What is the underlying cause most likely to be?

   • AA boundary issue in the block's collision box, where the push detection area is too large.
   • BA design flaw in the level layout, where the block is placed in a way that makes it slide from any direction.
   • CA logic error in the direction check, where the condition for allowed push directions is inverted or missing.
   • DAn unintended interaction with the player's movement speed, causing the block to slide on fast pushes.

   In a card game, a card that should draw two cards sometimes draws three. The code uses a loop that iterates over a list of effects. What is the most likely cause?

   • AAn unintended interaction with another card, which adds an extra draw effect.
   • BA logic error in the card's effect, where the draw count is hardcoded to three.
   • CA design flaw in the card's intended effect, where the designer actually wanted three draws.
   • DA boundary issue in the loop, where the loop runs one extra time due to an off-by-one error.

   A tester is testing a puzzle game where a switch must be activated to open a door. The tester finds that the door opens even when the switch is not activated, but only if the player stands in a specific corner of the room. What is the most likely cause of this defect?

   • AThe door's collision detection is faulty.
   • BThe player's character is too close to the door.
   • CThe door's opening animation is delayed.
   • DThe switch's activation area is too large and includes the corner.
